Meso-tetrakis(ferrocenylethynylphenyl) porphyrins: Synthesis and properties
摘要:
We report the synthesis of meso-tetrakis(ferrocenylethynylphenyl) porphyrins P1, P2 and the zinc derivative ZnP2. The photophysical and electrochemical properties of these porphyrins show substantial donor-acceptor interaction. The computational studies reveal that the para-linkage of the ferrocenyl unit in porphyrin P1 provides better pi-conjugation compared to meta-linkage in porphyrin P2, which results in low HOMO-LUMO gap and red shifted absorption. The porphyrin P2 and ZnP2 show better thermal stability compared to the porphyrin P1. (C) 2014 Elsevier B.V. All rights reserved.
